The main purpose of this study was to estimate the minimal detectable change
(MDC) on the Lawton Instrumental Activities of Daily Living (LIADL) scale in
community-dwelling patients with schizophrenia. Fifty-seven patients completed
the LIADL assessment twice, about 14 days apart.
Two scoring methods (dichotomous and polytomous) were used to record the patients' performance on the LIADL scale.
The MDCs of the LIADL scale were 1.5 (dichotomous)
and 4.4 (polytomous) points.
The MDC percentages were 22.0% (dichotomous) and 22.5% (polytomous), both of
which are within acceptable measurement errors.
The test-retest reliabilities of
the LIADL scale were both acceptable with two different scoring methods
(dichotomous = .75; polytomous = .76). Users can choose the scoring method
according to their individual needs.
